Reverting to a previous firmware version
You may need to revert to a previous firmware version if the upgrade did not install
successfully. The following sections will help you to backup your current
FortiAnalyzer 3.0 configuration, downgrade to FortiLog 1.6, and restore your
FortiLog 1.6 configuration.
The following topics are included in this section:
• Backing up your configuration using the web-based manager
• Downgrading to FortiLog 1.6
• Restoring your configuration
You can use the procedure, “To back up your configuration file in FortiAnalyzer 3.0
and higher using the web-based manager” on page 170 to back up your
FortiAnalyzer 3.0 configuration. Fortinet recommends backing up your
configuration file when upgrading, downgrading, reverting to factory defaults, or
installing a patch release.
Downgrading to FortiLog 1.6
When downgrading to FortiLog 1.6, no settings are carried forward. If you created
additional settings in FortiAnalyzer 3.0, make sure to back up the current
configuration before downgrading. See “Backing up your configuration” on
page 169 for more information.
To downgrade using the web-based manager
1 Go to System > Status > Firmware Version.
2 Select Update.
3 Type the location of the firmware version or select Browse.
4 Select OK.
The following message appears:
The new image does not support CC mode. Do you want to
continue to upgrade?
5 Select OK.
The following message appears:
This version will downgrade the current firmware version.
Are you sure you want to continue?
6 Select OK.
The FortiAnalyzer unit uploads the firmware image file, reverts to the old firmware
version, resets the configuration, restarts, and displays the FortiAnalyzer login.
This process takes a few minutes.
7 Log into the web-based manager.
Go to System > Dashboard > System Information to verify the Firmware
Version has changed to FortiLog 1.6.
